椎弓根钉内固定并椎间融合器治疗腰椎滑脱症手术前后X线对比

目的:探讨椎弓根钉内固定并椎间融合器治疗腰椎滑脱症的手术疗效。方法:应用全椎板减压椎弓根钉杆系统复位和固定椎间隙置入椎间融合器,治疗腰椎滑脱症38例。对所有病例进行术前和术后的X线检查,对滑脱程度、滑脱角、椎间隙后高等进行测量及评估。结果:术后所有患者滑脱均有不同程度复位,椎间隙后高、滑脱率、滑脱角均得到明显改善,生理曲度恢复。结论:椎弓根钉内固定并椎间融合器的治疗方法能使腰椎滑脱得到较为确实的复位和固定,有效恢复腰椎的生理曲度。

X-ray evaluation of pedicle screw fixation combined fusion cage for lumbar spondylolisthesis

Objective:To evaluate pedicle screw fixation combined fusion cage for lumbar spondylolisthesis using X-ray.Methods: The definitive reduction of the spondylolisthesis using pedicle Screw instrumentation was followed by primary reduction using intervertebral disc space distraction and interbody fusion with insert cages and local morselized bone after decompressive laminectomy.The radiographic data included slipping degree,slipping angle and posterior height of intervertebral space.Results: Post-operatively,the slipping degree reduced,the posterior heights of intervertebral space increased and slipping angle decreased.Conclusion: Pedicle screw fixation combined fusion cage for lumbar spondylolisthesis favored lumbar physiological curvature restoration.
